ASPNET: Server control: viewstate of child controls and LoadPostData

Hi experts,
I'm developing a CompositeControl which contains 3 child controls.
My problem is: when the page is posted back, the LoadViewState of my control is called before that of child controls, i.e. in the LoadViewState method, child controls are not ready. I want to find a place where the child controls' states are ready for use so that I can use them to restore some data field of the parent control. I try the LoadPostData method, but it is not called when the page is posted back like the document says.
So my questions are:
1. In what event the states of child controls are ready for use?
2. Why is the LoadPostData method not called?
Thank you for reading.

1. You should handle the Control's Load event instead.  See

2.  This method is used internally.  It is not supported.

1. I found another workaround for my problem.
2. It's so weird because the method is virtual and can be overriden.
Anyway, thanks for your help.
